Julia Wallerce / Vice Chair
Boston Program Manager, Institute for Transportation & Development Policy (ITDP)


Julia.pngA native of Northern California, Julia lives in Winthrop with her husband, daughter and corgi. Julia joined the LivableStreets Board in 2011 so she could start more conversations using her favorite urban planning jargon like 'spatial justice' and 'democratizing the streetscape', and ultimately to start putting visionary ideas into action. Julia and her daughter Maya have led the family bike ride for LivableStreets' largest annual fundraiser, Tour de Streets, every year since 2017, and she plays an integral role in fundraising and relationship building on the External Committee. She is most excited to continue to cultivate new donor relationships and build momentum around LivableStreets' Better Bus initiative. Julia is currently the Boston Program Manager for the Institute for Transportation & Development Policy (ITDP) where she leads efforts to pilot and pursue Bus Rapid Transit (BRT) in the Boston region, and is the Chair of the Winthrop Transportation Advisory Committee.

Stephen Gershman / Internal Committee Chair
Associate Director of Product Management, Wayfair


Stephen.pngStephen knows that the easiest way for people to connect to the LivableStreets mission is experiential — each day people enjoy traveling along greenways and wonder the best way to cross a street and reach a friend's home safely — that's why he likes telling new friends about the organization while out on a group run, bike, or drive. Stephen looks forward to seeing LivableStreets develop a playbook and leadership structure that will enable everyone to advocate effectively for complete streets in their communities. As Chair of the Internal Committee, Stephen helps with policy development and governance. He is currently an Associate Director of Product Management at Wayfair, building technology to provide the quality and personalized service experiences which customers love, at scale. Stephen enjoys recreating his favorite flavors in the kitchen, hiking new trails, and playing basketball.

Charles F. Denison IV
Sr. Applications Developer, Geode Capital Management


Charlie.pngCharlie lives in Boston's South End neighborhood and enjoys taking advantage of the many modes available in the city. He began as a volunteer for LivableStreets, joining the board in 2007 with a strong interest in strategic planning and the implementation of priority projects. For a number of years, Charlie was Chair of the Advocacy Committee, helping to organize and initiate advocacy efforts on projects across Metro Boston. In the last decade he estimates that he's penned more than 50 advocacy letters and likely contributed to hundreds more. Currently, Charlie is a major contributor to LivableStreets' social media presence, sharing the latest transportation-related news from around Boston and around the world. You're likely to see him on the streets of Boston taking photos of the latest parklets and bike lanes as well as things that need tweaking, like ill-timed pedestrian signals or confusing intersections. He currently sits on MassDOT's Design Exception Review Committee, reviewing and providing feedback on projects that do not meet MassDOT's minimum required pedestrian and bicycle accommodation. Through that committee, he also helps to advise MassDOT on how to improve design guidelines and review mechanisms to ensure that more projects meet and surpass the minimums. More recently, Charlie has joined the newly formed TransitMatters Advisory Council, which helps to advise their organization on transit-related issues in the metro-Boston area. Charlie is currently a Senior Applications Developer for Geode Capital Management, a financial services company in Boston. In his free time, Charlie enjoys traveling, studying political and social issues, and exploring the city.

Charlie says: Being a part of LivableStreets helped me to understand why most cities are so car-oriented. I also realized that passionate citizens have the power to change that paradigm, making moving people the priority rather than vehicles.

Jascha Franklin-Hodge
Executive Director of the Open Mobility Foundation


Charlie.pngJascha grew up in Brookline and has lived in South Boston since 2010. He has enjoyed getting around Boston by bike, foot, and public transit since he was a teenager, and wants his son to grow up in a city where he can safely, independently explore his community without a car.

He spends his days as the Executive Director of the Open Mobility Foundation, where he helps cities manage emerging mobility services (like shared bikes, cars, and scooters) using data and open source software. He previously served in the cabinet of Mayor Martin J. Walsh as the Chief Information Officer for the City of Boston, and was the co-founder and Chief Technology Officer of Blue State Digital.

Jason Lee
Founder and Principal, FMRA


Kenneth.pngJason Lee grew up in Vancouver, Canada, where unfortunately, he did not live in an igloo or commute to school via dogsled. He does sometimes slip up and say 'eh?' or pronounce words like about 'aboot'. For over a decade, he had the privilege of living and working as an affordable housing architect/urban designer in cities with great transportation infrastructure like Amsterdam, Toronto, and Shanghai. He is currently the founder and principal of FMRA, a strategic design consultancy that develops initiatives to build equity and inclusivity in the civic realm. Through his work with clients such as Boston Public Schools, the City of Boston, MassHousing, Smarter in the City and others, Jason recognizes the centrality of transportation infrastructure as a determinant of racial and economic equity. For this reason he views the work of LivableStreets as critical to closing the gaps that divide our communities across the city and the region. Jason is also a mentor with MIT's DesignX accelerator program and sits on their advisory board. He holds a bachelor's degree in Anthropology from McGill University and a Master of Architecture degree from the University of Toronto. In his free time, he loves to walk and mountain bike the Middlesex Fells Reservation adjacent to his town of Winchester with his family.

Emily Warren
Director of Policy, Nelson\Nygaard


Kathryn.pngEmily grew up in the auto-oriented suburbs of the San Francisco Bay Area, but is now delighted to live car-free in Somerville. An avid pedestrian, bike commuter, and recreational cyclist, she is passionate about expanding complete street infrastructure and multi-use paths throughout the region to support active transportation. Emily currently serves as a Venture Partner at Fontinalis Partners, a venture capital firm focused exclusively on investments in the transportation sector. Previously, she was one of the original employees at Lyft, where she lead the company's transportation policy team for several years, and at Lime, where she built the global policy and public affairs team from the ground up. She believes new mobility technologies can play an indispensable role in reducing reliance on car ownership - provided the right policies are in place to prioritize the public interest. When she's not caught up in wonky debates about mobility datasharing policy, running speed intervals around the Ellis Oval, or making a fool of herself at improv class, Emily can often be found walking her two beloved rescue dogs, Leo and Charlie, along the Somerville Community Path.
